Mod rewrite and 6.0005

I would like to make all urls in 6.0005 search engine friendly, my .htaccess file is only doing this for profiles. I am willing to pay anyone with the knowledge to write an .htaccess file which will apply the rewrite rule to classifieds, blogs, forums, events etc. I did purchase a mod which was supposed to do this but unfortunately it did'nt work and I had no response from the author. any help would be appreciated.
